It is very important to make sure you have good nutrition during pregnancy. You need more vitamins and minerals at this time, especially folic acid, iron and calcium for your baby to grow and develop. You need a few more calories as well, about 300 extra calories per day than you did before you became pregnant.
However, the CDC advises that because food is less nutrient-dense in these modern days it can be very difficult to obtain all the vitamins and minerals needed for pregnancy from food sources alone. In addition, for some women, many factors may make it hard to eat a well-balanced diet during pregnancy. Nausea and vomiting caused by morning sickness, food aversions, and certain diet restrictions (i.e. vegetarian diets) and health limitations (celiac disease or gluten sensitivity) may contribute to a deficiency in key nutrients that can result in unfavorable pregnancy outcomes. This is why taking a daily prenatal supplement may be a good idea to help you get all the vitamins and minerals that you and your baby need during pregnancy and breastfeeding.
